The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the stretch ahead.
Right off the bat, we've got a bit of a rough start. The first few days at Jaconé are a write-off. Saturday afternoon (5th September) is a no-go with rain, a shifty cross-onshore wind, and only a tiny 2ft SSE swell. The combined energy is a weak 95, so it’s not worth paddling out for. Sunday (6th) is worse – the swell jumps to 6ft, but it’s onshore and choppy, and the energy is 657. Not a pretty picture.
The first real glimmer of hope comes Monday afternoon (7th September). The wind shifts to a light cross-offshore breeze, cleaning up a 8ft SSW swell. The combined energy is a solid 1036, and while it’s big for beginners, it’s excellent for experienced surfers.
Tuesday morning (8th September) is also a goer, with a moderate offshore wind from the ENE and a 6ft S swell. The energy is 771, and it’s clean. That’s a decent session.
Then we hit a little lull. Wednesday (9th) and Thursday (10th) have glassy conditions but the swell drops off. Wednesday morning sees a 6ft E swell with 8-second period and glassy wind – that’s surfable, but it’s not the best of the run.
The standout window is Friday morning (11th September). Glassy conditions, a 4ft S swell with a very long 14-second period, and combined energy of 627. That’s clean, long-period groundswell wrapping in. The optimum swell direction is SE, and this is coming from the S, so it’s a good match. This is the best on offer for the first week. The water temp is around 73°, which is about 1° above normal – nothing out of the ordinary.
Saturday (12th) has a clean morning with a 4ft ENE swell and glassy conditions, but the period is short at 7 seconds. It’s a fun, small-wave option.
Things go quiet again from Sunday (13th) through Monday (14th) – strong onshore winds and tiny, messy surf. Not worth it.
The next solid period looks like Tuesday morning (15th September). Glassy conditions, a 5ft SSE swell with an 11-second period, and combined energy of 565. It’s clean and has good shape. That’s a solid mid-week option.
We get a bit of a mixed bag after that. Wednesday (16th) has a clean morning but only a 3ft SE swell. Thursday (17th) is mostly a washout with onshore winds.
The last real standout is Friday morning (18th September). A 6ft SSW swell with a very long 13-second period, and combined energy of 1240. The wind is a strong cross-offshore, keeping it clean. The swell is big, over 5ft, so it’s for intermediates and up. This is the best of the second week.
The run ends with a few small, clean days on Saturday (19th) and Sunday (20th) afternoon, but nothing to write home about.
So, the picks of the fortnight are Friday morning (11th) for the glassy, long-period groundswell, and Friday morning (18th) for the bigger, punchy SSW swell. Get out there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
